Description
また、点検後の作業において、放射された泡の回収も非常に手間がかかり、作業方法によってはその一部を排水路を通じて下水道に放出させる等環境を悪化させる可能性も含んでいた。
泡消火薬剤混合器6の点検に際しては、着色剤水溶液からなる擬似液を混合器6により水と比例混合し、その混合水溶液の吸光度を分光光度計による比色法で測定し、予め規定濃度に希釈した擬似液と吸光度の関係を求めて作成した検量線(図2参照)から、擬似液混合水溶液の混合率を求める。一方、混合器6のオリフィス径である条件を変えた時の、たん白泡原液と擬似液の混合率(%)を各々求め、得られた関係曲線(図3参照)から擬似液での混合率を測定することで、泡原液での混合器6の混合性能の是非を確認することができる。
なお、たん白泡原液の性能点検については、泡原液タンク5内の泡原液を少量採取し、別場所で簡易的に性能試験を実施する。この結果により、加圧送水装置4や混合装置6を含めた泡消火設備の総合的な性能点検を実施することができる。
Claims (1)
- オリフィスを備えた泡消火薬剤混合器により泡原液と水とを所定の混合率で混合させて泡水溶液を作るようにしている泡消火設備において、この泡消火薬剤混合器の混合性能を点検する方法として、着色剤水溶液からなる擬似液を前記混合器により水と比例混合し、その混合水溶液の吸光度を測定し、予め規定濃度に希釈した擬似液と吸光度の関係から、擬似液混合水溶液の混合率を求める一方、前記混合器のオリフィス径である条件を変えた時の前記泡原液と前記擬似液の混合率を各々求め、この求めた関係から擬似液での混合率を測定することで、泡原液での前記混合器の混合性能を確認することを特徴とする、泡消火薬剤混合器の点検方法。
